#wifi
Explainer , #BT #WiFi #communications. been off air for abit. The normal BT inadequacy, 'you are connected without internet'. Of course I've run the analysis, it ain't at my end & they see nothing at theirs. So, heh, an #engineer will call Weds 19th 8a.m. Better service in the 'badlands' out #Polish/#Ukrani border. Now hot desking wherever and whenever I can.
The chart shows the #homeassistant #glow #wifi signal strength. The left trace is before, the gap is when I disassembled it to solder the connector and the right trace is now. Also, you can see clearly when I closed the electric box door after reinstalling it: it's made of thin wood, but apparently is enough to drop the signal by like 5dBm
The signal is still weak, but if it stopped dropping the #connection, is enough for me!
Still no box, that will come when I stop experimenting...
Let's see it if made any difference (just hope I didn't make it worse...)
I scraped the #wifi #antenna contacts and cut the trace going to the rest of the internal antenna. Then soldered the cable with the #sma connector savaged from the #fonera . The shielding of the cable goes to GND (used the multimeter to find which one is GND) and the inner to the other antenna contact.
My brother had been using wifi battery monitors on his, his girlfriend's, and my cars for the last few years since we don't drive every day. Apparently they were dependent on a cloud service that the company discontinued, bricking them all! 
In looking up if anyone has found a way to use them without the cloud, I just found vendors still selling the now useless devices. The Deltran Battery Tender 081-0172.

I imagine -92dBm is not a really good figure
The electric box is at the end of a far corridor, in a part of the house where noone hangs around, so I'd prefer not to place a #WIFI repeater there.
Tonight I'll try to solder an external #antenna to the #esp32 like explained in the #homeassistant forum: https://community.home-assistant.io/t/how-to-add-an-external-antenna-to-an-esp-board/131601
I'll use the #fontenna (it's the #fon #fonera external antenna I savaged when I... ehm nuked the fonera flashing a firmware in the wrong partition
). Will see if it improves the situation...
Surveilling the Masses with Wi-Fi Positioning Systems

I didn't need to mess with the #photodiode trimmer, it did match already very well the electric #counter pulses.
The #esp32 struggled a lot to get wifi signal, we are very far from the access point, with multiple angled stone wall between. It's a miracle it could connect at all! I'll probably mod the #mcu to solder an external, bigger #wifi antenna.
Billions of Devices at Risk of Hacking Due to Hidden Commands

I love #ExtremeNetworks! They make great #wifi APs and as these APs are useless without their controller, they are really cheap (10-20€). But you can flash them with #OpenWrt and give them another life as a super affordable and super capable WiFi 5 AP. My house is pretty much stuffed with APs by ExtremeNetworks.
And as these things are meant for big installations, they got PoE and capable WiFi chips, some even got a USB port.
Yikes, from an article that contains a lot more detail, but just to get your attention as to the impact part:
«The ubiquitous ESP32 microchip made by Chinese manufacturer Espressif and used by over 1 billion units as of 2023 contains undocumented commands that could be leveraged for attacks.
The undocumented commands allow spoofing of trusted devices, unauthorized data access, pivoting to other devices on the network, and potentially establishing long-term persistence.
…
"Exploitation of this backdoor would allow hostile actors to conduct impersonation attacks and permanently infect sensitive devices such as mobile phones, computers, smart locks or medical equipment by bypassing code audit controls."
The researchers warned that ESP32 is one of the world's most widely used chips for Wi-Fi + Bluetooth connectivity in IoT (Internet of Things) devices, so the risk is significant.»
People worried about this topic might also "enjoy" the recent Netflix series Zero Day.
And not to get too far afield, but hopefully it also didn't escape notice that there have been broad firings of qualified people in the US government for reasons related not to their technical skill or ability to protect our nation from issues like this, but because of irrelevant details of their private lives or personal leanings on issues of having fair and competent government, helping the needy, defending individual human freedom and dignity, or avoiding mass death in myriad ever-more-likely ways.
Who approved this name? I get that there are two technological terms put together, but I think there's probably a better option here.
